7 claims. (c1. .eo-11) Our invention relates to a new and useful cutter andit relates. more particularly to a cutter4 especially well adapted for cutting brush and other under-growth in inaccessible places, our

5 novel cutter being provided with means for holdying the twig or branch to be cut while such twig is being severed, thus rendering our novel cutter operable with one hand automatically and without any attention on the part of the operator.

.In the accompanying drawing:

Fig. l represents a iront end elevation of the cutter embodying our' invention.

Fig. 2 represents a side elevation of Fig. 1 showing .the kcutter in its inoperative position.

Fig. 3 represents a fragmentary View partly in section and partly in elevation taken on line 3,--3 of Fig. l and showing details of construction.

Fig. 4 represents a view similar to Fig. 3 showing the device in the process of cutting a twig.

Fig. 5 represents a fragmentary section on line 5-5 of Fig. 2.

` Fig. 6 represents a section online 6 6 yoi Fig. 2. 1 y n Referring to the drawing, our novel cutter comprises a stem o1` shank I which may be of any desired length depending upon the use to which thev device is to be put, said stem being preferably formed of two channel members 2 and 3 positioned back to back and suitably securedin spaced relation to each other, as best seen in Fig. 6. The stem I is provided with any suitable handle d and is preferably deiiected as at 5 to facilitate operation and to facilitate access to the brush to be cut. The other end of the stem I terminates in a substantially straight portion 'I which forms a guide for the mounting and operation of the holding and cutting blades next to be described. The channel 2' is engaged by the slide 8 which carries the blade supporting member 9. The blade supporting member 9 either has integrally formed therewith or rigidly carries the blade I0 which projects at an angle to the guide l, as best seen in Figs. 2, 3 and 4. The blade I0, except for sliding longitudinally of the guide 1, is otherwise xed. The blade supporting member 9 is engaged by one end of the spring I I, the other end of which is anchored at I2 to the stern or shank I. I3 designates a stop for limiting the movement of the blade I0 in a direction away from the handle 4, the blade I0 and its supporting member 9 being pulled towards the handle yl when the pull on the device ceases. I5 designates a second blade which is pivoted at I6 tothe supporting member 9 which carries the blade I0, the blade I5 ,being normally inthe position shown in solid lines in Figs. Zand 3 in an out-of-the-way or inoperative position. rIn this position the blade I5 is prevented from further movement in the direction of the arrow in Fig..3 lby resting against the 5 yielding stop il'. The outer end of the blade I5 is curved, as at t9, to produce a cam effect which is adapted to cooperate-with the cam elementZll positioned in the outer end of the guide l.- `,The movement of the blade Stand theV blade supporting member 9 towards the handle 4 is limitedby the stop 2l. I,

The operation is as follows: When it isdesired to cut a twig 22, the device is held by the handle l and the front guide portionv l'thereof is inserted until the twig. 22 rests againstthe recess 23 in theblade I. The operator then pulls on the handle so thatthe blade I0, together with the supporting member 9, slides within the guide l against the tension ofthe kspring Il'. `l'ls the blade I and the supporting memberY 9 slide towards the outer end of the gui-de 'I therounded edge I9 of the blade I5 rides over thecam 2li; thus forcing the blade I 5 to project outwardly towards the 1 blade I0, as. shown in Fig-4. In thisv position thentwig 22is held fast inthe recess 23 between the blades I 0 and I5. Further pull on the handle 6l will exert further pressure on the blades lll and I5 and thus severs the twig 22 whereupon the blades I0 and I5 will assume the 30 position shown in dotted lines in Fig. 2.` Immediately after this position isreached the spring I I pulls the blade Ill away from the position shown in dotted lines to the position shown in solid lines in Fig. 2, and the yielding stop I1 acting on the rear outer en-d of the blade I5 serves to push it back into its inoperative position, as shown in Figs. 2 and 3. The device is now again ready for use.

It will be seen from the description of the parts and the explanation of the operation that by merely holding the cutter by the handle 4 with one hand the operator is able to extend the cutter into any out-of-the-way place which would otherwise be inaccessible to pruning shears or other devices necessitating the use of both hands in their operation. It will further be seenV that the cutting action is eiected by merely pulling onV the handle, and since it is obvious that the average person can exert more force by pulling than by attempting to operate shears with both hands away from the body it will be seen that our novel cutter is much more efficient, in that it enables the cutting of relatively thick brush, y twigs or branchesfwith the greatest ease. It '30 will be noted that the portion of the guide 'l which extends beyond the blade I is reduced to a minimum so as to constitute minimum obstruction in the manipulation of the device. The deilection of the shank I at 5, or in any other desired direction or to any other ldesired extent, renders it possible to operate the device successfully at points not in line with the direction of the hand of the operator. It will further be seen that the device can be made at a Very lowcost, due to its simplicity and the small number of parts and that the bla-des I0 and l5 are easily available for sharpening without removal from the guide l, although the removal of the blades from the guide 1 involves very little time or effort.

We claim:

1. A cutter of the character stated, comprising a shank, one end of which serves as a handle, a rigidly mounted blade longitudinally slidable at the other end of said shank, a second blade having pivotal relation to and slidable with said rst mentioned blade and a cam near the end of said shank for actuating said second blade into cutting relation with said rst blade.

2. A cutter of the character stated, comprising a shank, one end of which serves as a handle, a rigidly mounted blade longitudinally slidable at the other end of said shank, a second blade having pivotal relation to and slidable with said first mentioned blade, a cam near the end of said shank for actuating said second blade into cutting relation with respect to said rst blade and means for limiting the sliding movement of said blades.
